how it does this is through oil pressure to 'special' two piece lifters....when in the 4cyl, mode the outer part of the lifter moves with the cam, but the inner part does not move.. I E the pushrod nor valves move either...when the ECM sences a change in the load (going up a hill), or more gas (pedal position chages outside the limits) it switches back to 8cyl. mode... it does this in meer milliseconds and cant not be detected, other then the exhaust tone....as a matter of fact those DOD cylinders receive less ware do to this function....

Scoti,
welcome to the club.....you know we'll require a thread with pics

I talked with Howell feul injection as well as street and performance and both said it is not worth doing. So for my 05 5.3L who would you recomend getting a harness from so this function stays active? I am trying to get the best MPG I can out of this truck. It has 3.27RP with the 4L60E but the whole cylinder dropping has me at a loss at this point. Any imput would be great.

Also I missed it last time but nice job on slicing the rocker to fit the door/fender profile. Most poeple don't take the time to do this and it really pays off in the end.

I'm liking this very much. Great build and great pictures. I'm really facinated by your frame cut and splice. Great way to do that.

Go with the stock harness/PCM. You are more than capable of re-routing some wires. It looks worse than it is...

[68 short step]

yea, that would be my first choice (do it myself) but john at speartech is also another great option, he knows his stuff......
S&P is hit and miss on knowledge, enough so i dont base decisons on what they say...

Doing the harness is not that bad. Very scary looking and confusing at times with the mess of wires everywhere. Just do it one connector at a time and label everything... In the middle of doing mine and I quite enjoying it.... I do have one question for ya Don. Do you think it will affect the knock sensor reading if i route them inside the harness with the starter solenoid wire. They are a twisted pair of wires so I don't think induction should be a problem.
Thanx

I will contack John and get his imput. I would like to keep the DOD feature even if it only give a few % in gain on the MPG. I called S&P today to ask about CC on a drive by wire system and was pleased to find out it is all in their and all they would need to do is add a few wires for me to hook to my colunm switch. That will make for a very cloean set up. I assume John can do the same. Thanks for the info and I am heading over to read the link you sent.

I tried finding the link someone posted about the 'clean' apprearing turn signal stalk w/the CC switch. Do you happen to know that source?

i believe it was in my build up awhile back.

I knew it was in one of these threads but couldn't remember which one. I just re-read through Don's SS build-up as well as LowBuks & didn't see it. The Killer build-up was next on my list.....

That is the same one I have in Low Buck but it came with my CC kit that I ordered from a supplier that the manufacture recommended. I think the kit is a Rostra design or something like that. It works great now that I have all the dip switches adjusted right. I think summit or Jegs also sells the kits.

I was meaning to look into that CC switch. To make that functional all a guy has to do is add the CC input from that switch to the PCM, right?? I was shocked on how cheap it is!!

yes, the pcm controls the CC... just connect the on/off switch, resume/ accelerate, set....and you're done..

It's a Dakota Digital item...

are you going to use the fly by wire? we just wired up a 07 5.3 for a rail buggy and got the harness for the pedal from speartech. worked out perfect

yelp, keepin the DBW

Hey 68SS, What intake kit are you using with these gen4 engines and are you using the original MAF sensor to the engine???
Thanx.
Trevor

[68 short step]

i like to use the intake and air filter for a 00-02 denali/tahoe (aftermarket one)... and yes i keep the stock MAF and front O2s.... im not a huge speed density fan, especially for these GEN 3/4 engines

[tk-mpl]

Do you have a pic of the 6.2L intake setup yet?? Is there any mods to make the intakes fit?
Thanx.

[Ackattack]

how does it work with the ride height sensors? Does it try to adjust for body roll while going around a corner?

Found where to get my cruise control switch/turn signal!

none yet, no mods other then makeing a mounting bracket to support the weight of the tube/air filter....

yes, it sences the height of the suspension at any given time or load and adjusts it to your pre-sets....



some progress,
got the tranny lines mocked-up, on the 6l80e they come out of the driver side (unlike the 4l60e)...they are routed tightly under the tranny and then terminate into a AN tube adaptor....from there its just a few 90* and streight fittings, with bradided -6 line........


also doing the wiring, GM keeps switching PCM pins on me, so for all doing a swap 05-06 E38 computers are adiffrent from 07-08 38 computers... (computers are the same, just the pins that connect the wires to the PCM are diffrent) so i got some 07 E38 PCM pins comming...
here is the orginized mess

and a sneek peak at this
